Post tensioning Slab Load Testing

A building under construction experienced cracks on its post-tensioned slab. The structural capacity was questionable for a designed live load of 400 kg/m2 and a super imposed dead load of 250 kg/m2. Thus, a load test was conducted to determine the actual floor capacity.

Slab on ground Load Testing

RE conducted a load test on a ground slab in a factory on Suksawat road, Samut Prakan. In the design point of view, a ground slab is normally designed using the linear spring distribution support assumption. However, in reality, a ground slab often experiences nonlinear behavior. The slab on ground load test project was deemed necessary when there was a plan for new production line machines to be installed.

Steel Roof truss load test

Structural renovation has become more and more common in recent years. Due to the high concentration in urban areas, most land has already been occupied by existing structures which later on may be renovated for different uses.  However, due to deterioration over time or lack of maintenance, many existing structures may not be in a good condition for renovation which can then raise safety concerns. Thus, a load test is deemed necessary.

The Pull Out Test and The Shear Load Test on Anchor Bolts

The Pull Out Test is one of the methods used to inspect an anchor’s load carrying capacity. This test determines the tensile strength capacity. The tested load will be applied in the parallel direction to the anchor using a hydraulic pump with a load measuring system. Displacement of the tested anchor is measured by a displacement transducer which shows real-time data. The Pull Out Test conducted by RE complies with the ASTM E488-10 standard.
